Linearity of expectation is the property that the expected value of the sum of random variables is equal to the sum of their individual expected values.

The expected value of the sum of several random variables is equal to the sum of their expectations, e.g., E[X+Y] = E[X]+ E[Y] . On the other hand, the ...

If the value of Y affects the value of X (i.e. X and Y are dependent), the conditional expectation of X given the value of Y will be different from the overall ...

The linearity of expectation tells us that EY=EX1+EX2+⋯+EXn. We can also find the variance of Y based on our ...
